X-Ways Investigator comes at less than half the price of X-Ways Forensics, and considerable volume discount
for higher quantities is available. We recommend X-Ways Investigator
to organizations that also use X-Ways
Forensics, not necessarily as a stand-alone product! If before you buy you would like to know precisely how
the X-Ways Investigator user interface looks like and what it can
do, please enable the X-Ways Investigator GUI in the General
Options dialog window in X-Ways Forensics. The degree to which the
user interface is reduced and simplified is partially customizable.
X-Ways Investigator does not come with its own manual
and program help, instead the manual and help of
WinHex/X-Ways Forensics is used.

Interface for PhotoDNA (only for law enforcement),
which can recognize known
pictures (even if stored in a different format or
altered!) and can return the classification (CP,
relevant, irrelevant) to X-Ways Investigator

X-Ways InvestigatorCTR

X-Ways
Investigator CTR is a new even further reduced version of
X-Ways Investigator, which can open only the
evidence file
containers of X-Ways Forensics and X-Ways Investigator (raw
format or .e01 evidence file), no other
images an no disks/media. X-Ways
Investigator CTR is suitable exclusively as an add-on to
X-Ways Forensics when splitting up the analysis work across multiple
investigators/specialist or when providing files in containers to
lawyers or other people involved in the case, like an extremely
powerful viewer program for containers. Findings can be exported
from X-Ways Investigator CTR and imported back into the main case in
X-Ways Forensics if desired.

Further limitations compared to X-Ways
Investigator:

hash compuation and hash database not available

menu commands for exporting lists/subtrees
not available

only option to refine the volume snapshot:
metadata extraction

attaching external files not possible

GREP syntax not supported for searching

case log not included in case report

internal ID columns missing

All this for a price less than half of X-Ways
Investigator. To verify what functionality exactly is available in
X-Ways Forensics CTR, you can activate the user interface of X-Ways
Investigator CTR in the General Options dialog window in X-Ways
Forensics.
